An Objective Hardware Security Metric in Sight

Metrics

Security has been a domain blessed with an abundance of methods to improve in various ways, not so much in methods to measure the effectiveness of those improvements. With the best will in the world, absent an agreed security measurement, all those improvement techniques still add up to “trust me, our baby monitor camera is really… Read More

It should be no surprise in the current climate that the US government is ramping up investment in microelectronics security, particularly with an eye on China and investments they are making in the same area. This has two major thrusts as I read it: to ensure trusted and assured microelectronics are being used in US defense systems… Read More

When it comes to security we’re all outraged at the manifest incompetence of whoever was most recently hacked, leaking personal account details for tens of millions of clients and everyone firmly believes that “they” ought to do better. Yet as a society there’s little evidence beyond our clickbait Pavlovian responses that we’… Read More

Tortuga Crosses a Chasm

Tortuga Crosses a Chasm

Categories: IP, Security, Synopsys, Tortuga Logic

I assume you know the Geoffrey Moore “crossing the chasm” concept, jumping from early stage enthusiasts trying your product because they’ll try anything new, to expanding to a mainstream and intrinsically more critical audience – a much tougher proposition. I’d argue there may be more than one of these transitions in the… Read More

Can I Trust my Hardware Root of Trust?

Can I Trust my Hardware Root of Trust?
by Bernard Murphy on 02-28-2019 at 7:00 am
Categories: IP, Security, Tortuga Logic

Hardware Roots of Trust (HRoTs) have become a popular mechanism to provide a foundational level of security in a cell-phone or IoT device or indeed any device that might appear to a hacker to be a juicy target. The concept is simple. In order to offer credible levels of security, any level in the stack has to be able to trust that levels… Read More

One of the semiconductor topics that keeps me up at night is security. We track security related topics on SemiWiki and while the results are encouraging, we still have a very long way to go. Over the last three years we have published 148 security related blogs that have garnered a little more than 400,000 views. Security touches … Read More

Security and RISC-V

Security and RISC-V
by Bernard Murphy on 11-30-2018 at 7:00 am
Categories: Events, IP, RISC-V, Security, Tortuga Logic

One of the challenges in the RISC-V bid for world domination may be security. That may seem like a silly statement, given that security weaknesses are invariably a function of implementation and RISC-V doesn’t define implementation, only the instruction-set architecture (ISA). But bear with me. RISC-V success depends heavily… Read More

ARM TechCon 2018 is Upon Us!

ARM TechCon is one of the most influential conferences in the semiconductor ecosystem without a doubt. This year ARM TechCon has moved from the Santa Clara Convention Center to the much larger convention center in San Jose. Last year the conference seemed to be busting at the seams so this move makes complete sense. A little less … Read More

Webinar: Ensuring System-level Security based on a Hardware Root of Trust

Webinar: Ensuring System-level Security based on a Hardware Root of Trust

A root of trust, particularly a hardware root of trust, has become a central principle in well-architected design for security. The idea is that higher layers in the stack, from drivers and OS up to applications and the network, must trust lower layers. What does it help it to build great security into a layer if it can be undermined… Read More

Timing Channel Attacks are Your Problem Too

Timing Channel Attacks are Your Problem Too

Categories: IP, Security, Tortuga Logic

You’ve heard about Meltdown and Spectre and you know they’re really bad security bugs (in different ways). If you’ve dug deeper, you know that these problems are related to the speculative execution common in modern processors, and if you dug deeper still you may have learned that underlying both problems are exploits called timing… Read More
